Problems solved by technology

Therefore, in the two-channel shock absorber of Patent Document 1, setting of the natural frequencies of the vibration paths B and C by adjusting the rigidity (spring constant) of each spring and the weight (moment of inertia) of the intermediate flange The degree of freedom is reduced, and there is a concern that it is difficult to improve the vibration damping performance

Embodiment Construction

[0016] Next, modes for implementing the invention of the present disclosure will be described with reference to the drawings.

[0017] figure 1 is a schematic configuration diagram showing a starting device 1 including a vibration damping device 10 according to an embodiment of the present disclosure, figure 2 It is a sectional view showing the starting device 1 . The starting device 1 shown in these drawings is mounted on a vehicle equipped with an engine (internal combustion engine) as a prime mover. A pump impeller (input side fluid transmission member) 4 fixed to the front cover 3, a turbine wheel (output side fluid transmission member) 5 rotatable coaxially with the pump impeller 4, connected to a vibration damper 10 and fixed to an automatic transmission ( AT) or a continuously variable transmission (CVT) transmission input shaft IS, the damper hub 7, the lock-up clutch 8, etc. as power output components.

[0018] In addition, in the following description, "axial di...

Abstract

Provided is a damper device 10 comprising the following between a drive member 11 and a driven member 16: a first torque transmission path P1 that includes a first spring SP1, a first intermediate member 12, and a second spring SP2; and a second torque transmission path P2 that includes a third spring SP3, a second intermediate member 14, and a fourth spring SP4. The first and second springs SP1 and SP2 are arranged so as to be aligned along the circumferential direction of the damper device 10. The third and fourth springs SP3 and SP4 are arranged so as to be aligned along the circumferential direction of the damper device 10 more to the outside in the radial direction of the damper device than the first and second springs SP1 and SP2.

Description

technical field [0001] The present disclosure relates to a vibration damping device including an input member and an output member, wherein power from an internal combustion engine is transmitted to the input member. Background technique [0002] Conventionally, a dual-channel damper used in connection with a torque converter is known as the above-mentioned damper (for example, refer to Patent Document 1). In this damping device, the vibration path from the engine and the lock-up clutch to the output hub is divided into two parallel vibration paths B and C, and the two vibration paths B and C respectively have a pair of springs and are arranged on the Separate middle flange between pair of springs. In addition, in order to make the resonance frequencies of the two vibration paths different, the turbine of the torque converter is coupled to the middle flange of the vibration path B, so that the natural frequency of the middle flange of the vibration path B is lower than the ...
